MAIN FOR WATER-DISTRIBUTION.

PECLFICAI'EON forming part of Letters Patent No. 312,158, dated February 10, 1885.

Application filed February 28. 1884. (No model.)

: all whom it may concern:

Be it known that I, SAMUEL B. PEENEY, a citizen of the United States, residing at Evans ton, in the county of Cook, State of Illinois, have invented a new anduset'ul Improvement in Mains l'or .Vater-Distributiomof which the following is a specification.

The invention relates to an improved arrangement of pipes and valves to be used in freeing suction-mains and strainers of obstructions-such as sand, silt, and gravel in the said suction-mains, and leaves, weeds, and other like suspended matter, and ground or anchor ice on the said strainers.

Heretofore there has been no adequate apparatus for flushing the suction-mains and strainers located in the bed of a lake or pond without stopping the pumps, and it therefore often becomes necessary to stop the water-sup- 2 ply of towns and villages which draw their supply from lakes and ponds, when it is pumped directly into the supply-mains, and where occasional high winds in winter cause a stoppage of or greatly diminish the regular 2 supply by reason of a collection of ground or anchor ice upon the strainer, and at other seasons of the year by reason of the collection of leaves, weeds. and other like obstructions upon said strainers. A further annoy- 0 ing interference in the regular supply is the collection of sand, silt, and gravel in the said suction-mains, which obstructions arise by reason of the action of the water from high winds, which stir up the sedimentary matter at 3 5 the bottom of the lake. These latter obstructions in the suction-mains not only cause temporary stoppage of the machinery for the purpose of clearing them out, but the suspended fine grit will pass through the pumps 0 by reason of the contracted area of the free opening in said suction-mains, caused by the lodginent of said silt, sand, and gravel in them, and the said fine grit will cause permanent injury and early destruction of the 5 pumps, cylinders, pistons, and valves.

The object of my invention is to provide means of reversing the current of water in the suction-mains t'orthe purpose of forcing outthe obstruct-ions without stopping the pumping 5o machinery,and without materially interfering with the distribution of the water in the town or village.

My improvement consists in a new and useful arrangement of by-pass pipes and valves,

whereby the water is caused to flow back at 5 a rapid rate for a short time, and thus force out the obstructions.

In the accompanying drawings, Figure l isa plan of a duplex system. Fig. 2 is a plan of a single system, and Fig. 3 is a plan of a modi- 6 tied single system having double suction-pipes, each of which embodies my improvements.

In Fig. 1, from the double strainer box or crib O O, suitably situated and anchored un der water in the usual manner, suction-pipes 6 A and B extend to the pumps E and D, respectively,which, together with the delivery pipes J J J and their necessary appurtenauces,constitute the usual duplex pumping system for distributing water to towns and villages.

To apply one of my by-pass systems to the said usual system, as described, I add the pipes F, H, and K and the valves 1, 2, 3, 4, 5,

6, and 7, all preferably of capacity equal to that of the suction-mains A and B. The operation of this sytem is as follows: The pump E being stopped and the pump D being in motion drawing water from the crib 0 through pipe 13, valves 4 and 7 being opened and valves 2 and 5 closed and forcing water through pipes J and J-first, if it is desired to flush pipe A or clear strainer of the crib O of anchor ice and other obstructions, open valve 1. The course of the water will then be to the pump 8 D through pipe B, and from the pump D in the direction of least resistance through the pipes K and A; second, the conditions being the same as aboveviz., pump D running and pump E stopped-if it is desired to flush the 0 pipe B or clear strainer 0, first open valves 3 and 5 and close valve 4, valve 1 being closed already, and, lastly, open valve 2. The course -of the water will then be to the pump D through pipes A and H, and from the pump 5 D through the pipes F and B. If pump E is in motion and pump D stopped, then the order of operating the valves will be symmetrically changed-that is to say, according to the uses of this system, already indicated, if pump :00

. and pipe F.

The operation of this single system is as follows: The pump D being in motion, drawing water from crib 0 through pipe Bvalve 2 being closed-and forcing water through pipe J, if it is desired to flush pipe B or clear the strainer of crib 0, open valve 2. The course of the Water will then be from pump D in the direction of least resistance, which will be through pipes F and B. In this instance the water used in said flushing and clearing, after the first supply through valve 2, may be either the backflow from the supply-mains of the village or city, or it may come through the pump D from a well, which is frequently in such water-works located between the crib and the pump on either side of valve 7.

In Fig. 3 (representing in plan a single pump with double suction pipe) the double crib G O, suction-pipes A and B, pump D, delivery-pipes J and J, with their necessary appurtenances, constitute an improved single system, having facilities which allow of one suction-pipe and strainer being used while the other is disabled or undergoing repairs.

To apply myinvention to this system I add the pipes Fand K, Fig. 3, and the valves 1, 2,

6, and 7.

The operation of my invention in this sys tem, referring to Fig.3, is as follows: The pump D beingin motion, all valves closed except 7-first, if it is desired to flush pipe A and to clear the crib and strainer 0, open valve 1. The course of the water will then be in the direction of least resistance through pipes K and A.

If it is desired to flush pipe B, the conditions being as aboveviz. all the valves closed except valve 7first open valve 6. Then close valve 7 and open valve 2. The course of the water will then be to the pump through pipes A, and from the pump in the direction of least resistance through pipes F and B.

It is evident that this invention is applica' ble to any hydraulic system.

Vhat I claim, and desire to secure by Letters Patent, is

In asystem of water-distribution, the crib, pump, and suction and delivery pipes, combined, substantially as set forth, with an independent flushing-pipe connecting the suction and delivery pipes, and valves located in said independent flushing and suction pipes, where by the current normally drawn through the crib may be reversed and the crib and suctionpipes cleared of obstructions, as specified.
